The fixed rail 31a is fixed to both side walls of the inner box 20 with the fixed rail 31a, the moving rail 31b, the intermediate running rail 31c, and the bearing 31d pre-installed. Then, the respective storage chambers and the storage chamber doors are connected by fixing the moving rails 31b to the respective storage chamber doors.

なお、固定レール３１ａと移動レール３１ｂと、固定レール３１ａと移動レール３１ｂとの間にベアリング３１ｄを介して配設した中間走行レール３１ｃとからなるレール部材３１は予め組み込んだものであり、それぞれのレール間のクリアランスを最小限に設定することができる。 In addition, the rail member 31 which consists of the fixed rail 31a, the moving rail 31b, and the intermediate | middle traveling rail 31c arrange | positioned via the bearing 31d between the fixed rail 31a and the moving rail 31b is integrated beforehand, The clearance between the rails can be set to a minimum.

Then, the vegetable compartment container 32a and the freezer compartment container 32b are detachable in the upward direction when they are moved back and forth together with the moving rail 31b and each storage compartment door is at least fully opened. At this time, the vegetable compartment container 32a that is the upper storage chamber is supported by attaching the rail member 31 at least to the lower side from the central portion in the height direction, and the freezer compartment container 32b that is the lower storage chamber is supported in the height direction. A rail member 31 is attached and supported at least on the upper side from the center.

また、レール部材３１の固定レール３１ａは位置規制手段である補強部材３３によってそれぞれ内箱２０を介して固定位置を規制される。 Further, the fixed position of the fixed rail 31a of the rail member 31 is restricted via the inner box 20 by the reinforcing member 33 which is a position restricting means.

また、上下に隣接した貯蔵室に備えてある複数のレール部材３１の同一側方に配置した複数の固定レール３１ａを１枚の補強部材３３で一体に固定することで、貯蔵室間の前後、上下、左右のレール部材３１の位置規制ができる。そして、補強部材３３は、内箱２０の発泡断熱材２２を充填した側に配置されるので補強部材３３は各貯蔵室内に露出しない構造となっている。 In addition, by fixing a plurality of fixed rails 31a arranged on the same side of the plurality of rail members 31 provided in the upper and lower adjacent storage chambers with one reinforcing member 33, the front and rear between the storage chambers, The position of the top and bottom and left and right rail members 31 can be regulated. And since the reinforcement member 33 is arrange | positioned at the side filled with the foam heat insulating material 22 of the inner box 20, it has the structure where the reinforcement member 33 is not exposed in each storage chamber.

また、補強部材３３の両端はそれぞれ野菜室２７の下部付近、冷凍室２８の上部付近まで達し、各貯蔵室内の左右のレール部材３１の固定レール３１ａは補強部材３３の固定部３３ｃに固定され、少なくとも補強部材３３の固定部３３ｃは内箱２０の発泡断熱材２２を充填した側の面に接している。 Further, both ends of the reinforcing member 33 reach the vicinity of the lower part of the vegetable compartment 27 and the vicinity of the upper part of the freezing compartment 28, and the fixed rails 31a of the left and right rail members 31 in each storage room are fixed to the fixing portions 33c of the reinforcing member 33, At least the fixing portion 33c of the reinforcing member 33 is in contact with the surface of the inner box 20 on the side filled with the foam heat insulating material 22.

また、補強部材３３は線膨張率が１．０〜３．０×１０−６ｃｍ／ｃｍ・℃である材料にて形成されることが望ましい。また、熱伝導率が０．１〜０．２Ｗ／ｍ・Ｋである材料にて形成されることが望ましい。 The reinforcing member 33 is preferably formed of a material having a linear expansion coefficient of 1.0 to 3.0 × 10 −6 cm / cm · ° C. Moreover, it is desirable to form with the material whose heat conductivity is 0.1-0.2 W / m * K.

また、ベアリング３１ｄは回転支持部材であればよく、たとえばローラ等を用いてもよい。 The bearing 31d may be a rotation support member, and for example, a roller or the like may be used.

以上のように構成された冷蔵庫について、以下その動作、作用を説明する。 About the refrigerator comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

まず、各貯蔵室ドアを手前に引出すと各貯蔵室の両側部に備えられたレール部材３１の移動レール３１ｂと中間走行レール３１ｃとが回転支持部材３１ｄが回転することにより滑らかに手前側に摺動する。 First, when each storage room door is pulled out, the moving rail 31b of the rail member 31 and the intermediate traveling rail 31c provided on both sides of each storage room are smoothly slid toward the front side as the rotation support member 31d rotates. Move.

それに伴い、レール部材３１に支持された容器３２も手前に引出され、容器３２内に収納された被冷却物の取出し及び新たな被冷却物の収納が可能となる。 Accordingly, the container 32 supported by the rail member 31 is also pulled out to the front, and the object to be cooled stored in the container 32 can be taken out and a new object to be cooled can be stored.

このとき、固定レール３１ａと移動レール３１ｂとをあらかじめ組み込んだ状態のレール部材３１を内箱２０の両側壁面に固定することにより固定レール３１ａと移動レール３１ｂとのクリアランスを小さくすることができ、ガタの少ない高品位な引出しを構成することができる。また、クリアランスを小さくすることにより取付けのバラツキも小さくできるのでドアの取付け不具合による傾きや他のドアとの間隔の不均一化という外観不良も抑制することができる。これらの効果はレール部材３１の引出し代が大きいほど効果的である。また、固定レール３１ａと移動レール３１ｂとの間を回転支持部材であるベアリング３１ｄで支持することにより野菜室、冷凍室容器３２ａ、３２ｂに荷重を加えた場合でも滑らかに移動レール３１ｂが移動できるので引出しの操作力を低減することができ、使い勝手の向上を図ることができる。 At this time, the clearance between the fixed rail 31a and the movable rail 31b can be reduced by fixing the rail member 31 in a state in which the fixed rail 31a and the movable rail 31b are preliminarily assembled to both side walls of the inner box 20, thereby reducing the backlash. A high-quality drawer with a small amount can be configured. In addition, since the variation in mounting can be reduced by reducing the clearance, it is possible to suppress the appearance defect such as the inclination due to the door mounting failure and the non-uniform spacing with other doors. These effects are more effective as the allowance for the rail member 31 is larger. Further, since the fixed rail 31a and the moving rail 31b are supported by a bearing 31d that is a rotation support member, the moving rail 31b can move smoothly even when a load is applied to the vegetable compartment and freezer compartments 32a and 32b. The operation force of the drawer can be reduced, and the usability can be improved.

また、補強部材３３によりレール部材３１の固定レール３１ａの取付位置を規制することでレール部材３１の前後、左右、上下寸法あるいは平行度が規定どおりに保持できることと、補強部材３３により断熱箱体１９の発泡断熱材２２充填後の冷却時の熱収縮等による寸法変化を抑制することで、固定レール３１ａと移動レール３１ｂとのクリアランスを小さく設定したレール部材３１をあらかじめ組み込んだ状態で内箱２０の両側壁面に固定する仕様としても左右一対のレール部材３１間の寸法精度を高く保てるので容器３２の引出し時の操作性を、位置規制手段である補強部材３３により高めることができる。また、長期にわたって操作信頼性の確保も図ることができる。 Further, by restricting the mounting position of the fixed rail 31 a of the rail member 31 by the reinforcing member 33, the front and rear, left and right, vertical dimensions or parallelism of the rail member 31 can be maintained as prescribed, and the heat insulating box body 19 by the reinforcing member 33 Of the inner box 20 with the rail member 31 in which the clearance between the fixed rail 31a and the movable rail 31b is set small in advance, by suppressing the dimensional change due to heat shrinkage or the like during cooling after the foam insulation material 22 is filled. Since the dimensional accuracy between the pair of left and right rail members 31 can be kept high even in the specification of fixing to both side wall surfaces, the operability when the container 32 is pulled out can be enhanced by the reinforcing member 33 which is a position restricting means. In addition, it is possible to ensure operation reliability over a long period of time.

また、左右一対の補強部材３３に複数のレール部材３１の固定レール３１ａを固定したので部品点数の削減によるコストダウンを図ることができる。 Further, since the fixed rails 31a of the plurality of rail members 31 are fixed to the pair of left and right reinforcing members 33, the cost can be reduced by reducing the number of parts.

また、上部貯蔵室である野菜室容器３２ａは、高さ方向の中央部より少なくとも下部側方にレール部材３１を取付けて支持し、下部貯蔵室である冷凍室容器３２ｂは、高さ方向の中央部より少なくとも上部側方にレール部材３１を取付けて支持しているので、補強部材３３を小型化することができ、それによりコストの低減及び、野菜室２７と冷凍室２８に接する表面積も縮小されることになり上下の貯蔵室間の補強部材３３からの熱伝達を抑制し、温度帯の高い野菜室２７側の結露の防止や熱リークによる消費電力の増加を抑制できる。 Moreover, the vegetable compartment container 32a which is an upper store room attaches and supports the rail member 31 at least to the lower part side from the center part of a height direction, and the freezer compartment container 32b which is a lower store room is the center of a height direction. Since the rail member 31 is attached and supported at least on the side of the upper part, the reinforcing member 33 can be reduced in size, thereby reducing the cost and the surface area in contact with the vegetable compartment 27 and the freezer compartment 28. Therefore, heat transfer from the reinforcing member 33 between the upper and lower storage rooms can be suppressed, and condensation on the side of the vegetable room 27 having a high temperature zone can be prevented and an increase in power consumption due to heat leakage can be suppressed.

また、補強部材３３を各貯蔵室内に露出させないようにしたので補強部材３３を各貯蔵室内部に配置した場合に比べ収納内容積の低減を抑制することができる。 Further, since the reinforcing members 33 are not exposed in the respective storage chambers, it is possible to suppress the reduction of the storage volume as compared with the case where the reinforcing members 33 are arranged in the respective storage chambers.

また、補強部材３３を金属材料で形成した場合に端面のエッジによる怪我を防止できるので安全性を向上させることができ、更に端面のエッジ削除処理を廃止できるのでコストダウンを図ることができる。 Further, when the reinforcing member 33 is made of a metal material, it is possible to prevent injuries due to the edge of the end face, so that the safety can be improved, and furthermore, the edge deletion process of the end face can be abolished, thereby reducing the cost.

また、左右の固定レール３１ａを連結する補強部材３３を断熱箱体１９の発泡断熱材２２内に埋設したので、冷蔵庫１８の使用時に補強部材３３の結露，着霜の防止を図ることができ、更に補強部材３３が空気と接することが無いので補強部材３３の耐食性を向上させることができ、補強部材３３の防錆処理も軽減できるのでコストダウンを図ることができる。 Further, since the reinforcing member 33 that connects the left and right fixed rails 31a is embedded in the foam heat insulating material 22 of the heat insulating box 19, it is possible to prevent condensation and frost formation of the reinforcing member 33 when the refrigerator 18 is used. Further, since the reinforcing member 33 does not come into contact with air, the corrosion resistance of the reinforcing member 33 can be improved, and the rust prevention treatment of the reinforcing member 33 can be reduced, so that the cost can be reduced.

また、補強部材３３の周辺に発泡断熱材２２があることで補強部材３３の取付け強度も向上し、位置規制の信頼性やレール部材３１の取付け強度の向上を図ることができる。 Further, since the foamed heat insulating material 22 is provided around the reinforcing member 33, the mounting strength of the reinforcing member 33 can be improved, and the reliability of position regulation and the mounting strength of the rail member 31 can be improved.

また、補強部材３３の線膨張率を１．０〜３．０×１０−６ｃｍ／ｃｍ・℃とした線膨張率が小さい材料で形成することにより、冷蔵庫１８の運転時に補強部材３３が収縮することによる操作性への影響を低減できるのでレール部材３１の操作信頼性を向上することができる。 Further, the reinforcing member 33 is contracted during operation of the refrigerator 18 by forming the reinforcing member 33 with a material having a low linear expansion coefficient of 1.0 to 3.0 × 10 −6 cm / cm · ° C. Since the influence on the operability due to this can be reduced, the operation reliability of the rail member 31 can be improved.

また、補強部材３３の熱伝導率を０．１〜０．２Ｗ／ｍ・Ｋとしたので熱伝導率が小さい材料で形成することにより、特に複数の貯蔵室の温度帯が異なる場合に補強部材３３からの熱伝達を抑制し、温度帯の高い貯蔵室側の結露の防止や熱リークによる消費電力の増加を抑制できる。 In addition, since the thermal conductivity of the reinforcing member 33 is 0.1 to 0.2 W / m · K, the reinforcing member 33 is formed of a material having a low thermal conductivity, particularly when the temperature zones of the plurality of storage chambers are different. It is possible to suppress heat transfer from 33, prevent condensation on the side of the storage room having a high temperature zone, and suppress an increase in power consumption due to heat leakage.

なお、本実施の形態ではレール部材３１と野菜室、冷凍室容器３２ａ、３２ｂとを共通の材料としたが、実使用の収納形態などによりそれぞれ貯蔵室別に違う材料で形成したものを使用するとさらにコスト低減、信頼性向上を図ることができる。 In this embodiment, the rail member 31, vegetable room, and freezer compartments 32a and 32b are made of a common material. However, if a different material is used for each storage room depending on the actual storage form, etc. Cost reduction and reliability improvement can be achieved.

また、補強部材３３は線膨張率が１．０〜３．０×１０−６ｃｍ／ｃｍ・℃、熱伝導率が０．１〜０．２Ｗ／ｍ・Ｋである材料としたが、一般的には線膨張率に関しては金属類が１．０〜３．０×１０−６ｃｍ／ｃｍ・℃で樹脂類は１．０〜１５．０×１０−５ｃｍ／ｃｍ・℃であり、熱伝導率は金属類が１．０〜４００．０Ｗ／ｍ・Ｋで樹脂類は０．１〜０．２Ｗ／ｍ・Ｋである。 The reinforcing member 33 is made of a material having a linear expansion coefficient of 1.0 to 3.0 × 10 −6 cm / cm · ° C. and a thermal conductivity of 0.1 to 0.2 W / m · K. In terms of linear expansion coefficient, metals are 1.0 to 3.0 × 10 −6 cm / cm · ° C. and resins are 1.0 to 15.0 × 10 −5 cm / cm · ° C. Is 1.0 to 400.0 W / m · K for metals and 0.1 to 0.2 W / m · K for resins.

従って、補強部材３３の材料としては冷蔵庫１８の運転時にレール部材３１の取付け位置精度が要求される場合には線膨張率の小さい金属類を使用し、温度帯の高い貯蔵室側の結露の防止や熱リークによる消費電力の増加の抑制が要求される場合には熱伝導率の小さい樹脂類を使用することがのぞましい。また、複数の貯蔵室に対して両者を一体化して用いてもよい。 Therefore, when the mounting position accuracy of the rail member 31 is required during the operation of the refrigerator 18 as the material of the reinforcing member 33, metals having a low linear expansion coefficient are used to prevent condensation on the storage room side having a high temperature zone. When it is required to suppress the increase in power consumption due to heat leaks, it is preferable to use resins with low thermal conductivity. Moreover, you may integrate and use both with respect to several storage chambers.

なお、本実施の形態では、野菜室２７と冷凍室２８にレール部材３１を用いたもので説明したが、引出し容器を備えた貯蔵室に適宜適用できる。たとえば、野菜室２７の上部に位置する切替室２５や、切替室２５の横に併設した製氷室（図示せず）等に用いてもよい。 In the present embodiment, the vegetable member 27 and the freezer compartment 28 are described as using the rail member 31, but can be appropriately applied to a storage room provided with a drawer container. For example, you may use for the switching room 25 located in the upper part of the vegetable compartment 27, the ice making room (not shown) attached to the side of the switching room 25, etc.

また、本実施の形態では、補強部材３３は野菜室２７と冷凍室２８のそれぞれのレール部材３１を一体に固定したもので説明したが、野菜室２７と冷凍室２８のそれぞれに両端に垂直部を有する断面コの字状の補強部材を用いてもよい。この場合、野菜室２７と冷凍室２８が上下に併設していない冷蔵庫において、それぞれガタツキの少ない高品位かつ荷重を加えても操作力の小さい使い勝手の良い引出しを提供することができる。また、複数のレール部材を一つの補強部材に固定した場合に比べ複数の貯蔵室の温度帯が異なる場合に更に補強部材からの熱伝達を抑制し、温度帯の高い貯蔵室側の結露の防止や熱リークによる消費電力の増加を抑制できる。 Moreover, in this Embodiment, although the reinforcement member 33 demonstrated what fixed each rail member 31 of the vegetable compartment 27 and the freezer compartment 28, it is perpendicular | vertical to both ends in the vegetable compartment 27 and the freezer compartment 28, respectively. A U-shaped reinforcing member having a cross section may be used. In this case, in a refrigerator in which the vegetable compartment 27 and the freezer compartment 28 are not provided vertically, it is possible to provide an easy-to-use drawer with a small operation force even when a high quality and load with little backlash are applied. In addition, heat transfer from the reinforcing members is further suppressed when the temperature zones of the plurality of storage chambers are different compared to the case where a plurality of rail members are fixed to one reinforcing member, and condensation on the storage chamber side having a high temperature zone is prevented. And increase in power consumption due to heat leakage can be suppressed.

なお、左右の一対のレール部材の固定レールを複数の補強部材で連結してもよい。この場合、補強部材を複数に分割することにより補強部材の小型化を図れるのでコストダウン、軽量化を図ることができる。 In addition, you may connect the fixed rail of a pair of rail member on either side with a some reinforcement member. In this case, since the reinforcing member can be reduced in size by dividing the reinforcing member into a plurality of parts, the cost can be reduced and the weight can be reduced.

以上のように、本発明にかかる冷蔵庫は、ガタが小さく、容器に荷重を加えた場合でも滑らかに引出しを開閉することができ、高品位で使い勝手の良い引出し収納ができるので、冷凍装置を備えた冷却貯蔵庫の引出し装置等の用途にも適用できる。 As described above, the refrigerator according to the present invention is small in play, can open and close smoothly even when a load is applied to the container, and has a high-quality and easy-to-use drawer storage. It can also be applied to applications such as a cooling storage drawer.
